Simple swab test cuts powerful antibiotic use in ICU, study finds

This study tested if quickly telling doctors the result of a negative nasal swab test could reduce the use of a strong antibiotic called vancomycin in critically ill adults with pneumonia. Vancomycin is often given 'just in case' for a rare infection, but it carries serious risks like kidney damage. The trial involved 277 patients and compared sending a pager alert about the swab result to doctors versus usual care, to see if it safely reduced unnecessary antibiotic treatment.
